LB-2607 Leak and Seal Positive Pressure Strength Tester (High-Definition Touchscreen)

Name: LB-2607 Leak and Seal Positive Pressure Strength Tester (High-Definition Touchscreen)
Brand: Laibote (Tianjin) Testing Machinery
Availability: InStock

This method is applicable to plastic bottle caps conforming to the relevant standard. A puncture fixture is used to apply pressure to bottle samples, creating an internal–external pressure differential in the sample immersed in water. The release of gas from the sample is observed to evaluate its sealing performance.

LB-2607 Leak and Seal Positive Pressure Strength Tester (High-Definition Touchscreen)

Description

Product Introduction:

Reference standard:

GB/17876, ASTM F1140, ASTM F2054, ISO 11607, GB 18454, GB/T 1004, GB/T 1005, GB 19741, BB/T 0003, QB/T 1871.

Test principle:

Leak Test: After reaching the set pressure, maintain that pressure without replenishing it. If the pressure drop during the hold period exceeds the specified threshold, the sample is deemed non‑conforming; if the pressure drop remains within the threshold, the sample is deemed conforming.
Burst test: Once the pressure reaches the threshold, the burst‑detection phase begins; the test is stopped when the pressure drops to within a specified percentage of the maximum pressure, at which point the system automatically releases the air. During this process, the screen displays the recorded maximum pressure value. Pressure is regulated via the pressure‑adjustment valve on the side of the device; it is recommended to increase the pressure gradually to prevent rapid pressurization, which could lead to uneven pressure distribution between the sensor and the sample interior and introduce measurement errors.
Pressure Holding/Creep: Once the set pressure is reached, pressure holding begins. During the holding phase, if the pressure drops to (1 − accuracy%) of the set value, a compensating pressure boost is applied to maintain the target pressure. If, during the holding phase, the pressure decline reaches the predefined threshold, the specimen is deemed to have ruptured, the test is terminated, and the specimen is classified as non‑conforming.
Creep to burst: After reaching the set pressure, maintain constant pressure. During the hold phase, if the pressure drops to (1 − accuracy%) of the set value, a pressure‑boosting step is performed to sustain the pressure. If, during the hold phase, the pressure drop reaches the predefined threshold, the test is deemed to have reached the sample’s burst point; pressure holding is then terminated, timing stops, and the timer is not reset.
Large‑scale leakage: Use a dedicated clamping fixture to press the bag underwater, inflate the test bag to a specified pressure, and visually inspect for leaks. The test duration is manually controlled and can be stopped by pressing the stop button.

Product Features:

Button controls make operation simpler and data results more intuitive.
The test barrel is made of highly transparent acrylic, making it sturdy and durable.
Specialized plastic bottle cap puncturing fixture, ensuring no air leakage.
One-click operation: automatically start the test with a single click, automatically terminate the experiment, and automatically release pressure.
It features a sample library with preset test parameters; includes a product test result marking function to retain historical test data; and provides graphical curves for more intuitive data visualization.
7-inch large display, supporting user permission management, Chinese–English language switching, data storage, and audit trail (optional)
